Traditional multi-type code recognition switching optical lens structures have limited switching speed, fluctuating image quality, and high control complexity. In order to achieve the requirements of modern multi-type code recognition, a new type of multi-type code recognition switching optical lens structure is used.

[0003] In existing technologies, traditional scanning equipment often uses fixed illumination as the light source. When it is necessary to change the lens body, manual operation is usually required, which is inefficient and prone to errors, making it difficult to meet the high-speed operation requirements of automated production lines. Utility Model Content

When it is necessary to change the lens body, manual operation is usually required, which is inefficient and prone to errors, making it difficult to meet the high-speed operation requirements of automated production lines.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-3An embodiment of this utility model provides a multi-type code recognition switching optical lens structure, including a housing 1. A first motor 11 is fixedly connected to the inner wall of the housing 1. A first gear 12 is fixedly provided at the output end of the first motor 11. The tooth end of the first gear 12 is meshed with a rack body 13. The outer wall of the rack body 13 is slidably connected to the inner wall of the housing 1. A spring limiting rod 14 is fixedly connected to the inner wall of the rack body 13. A buffer tooth 15 is slidably connected to the outer wall of the spring limiting rod 14. The tooth end of the buffer tooth 15 is meshed with the tooth end of the first gear 12. A limiting slide rail 16 is slidably connected to the outer wall of the rack body 13. The lower surface of the limiting slide rail 16 is fixedly connected to the inner wall of the housing 1. A rotating rack 17 is fixedly connected to the lower surface of the housing 1. A sector gear 18 is meshed with the tooth end of the rotating rack 17. A light source 19 is fixedly connected to the inner wall of the sector gear 18. The outer wall of the light source 19 is rotatably connected to the inner wall of the rack body 13. A switching component is provided on the upper surface of the housing 1.

[0027] Specifically, the first motor 11 fixed on the outer casing 1 drives the first gear 12 to move, causing the rack body 13 to slide on the inner wall of the limiting slide rail 16. When it moves to a certain position, the first gear 12 pushes the buffer tooth 15 to move, causing the spring part on the spring limiting rod 14 to be compressed, thereby enabling the light source 19 to stay at one end for scanning. When the lens needs to be replaced, during the movement, the sector gear 18 causes the light source 19 to rotate under the action of the rotating rack 17 fixed on the lower surface of the outer casing 1. This not only enables the light source 19 to stay and continuously scan the same type of code, but also facilitates the replacement of the lens body 36.

[0028] Reference Figure 1 and Figure 4 The switching assembly includes a bracket 2, the inner top wall of which is fixedly connected to the upper surface of the outer shell 1. A fixing block 21 is fixedly connected inside the bracket 2. A second motor 22 is fixedly connected to the inner wall of the fixing block 21. A second gear 23 is fixedly provided at the output end of the second motor 22. A gear ring 24 is meshed with the tooth end of the second gear 23. The outer wall of the gear ring 24 is rotatably connected to the inner wall of the fixing block 21. A rotating plate 25 is fixedly connected to the front outer wall of the gear ring 24. The rear outer wall of the rotating plate 25 is slidably connected to the front outer wall of the fixing block 21. A clamping assembly is provided on the front outer wall of the rotating plate 25.

[0029] Specifically, starting the second motor 22 fixed to the inner wall of the fixed block 21 drives the second gear 23 to rotate, causing the gear ring 24 to rotate. The gear ring 24 drives the rotating plate 25 to rotate, thereby achieving the switching effect. The set bracket 2 can provide support for the whole.

[0030] Reference Figure 1 and Figure 5The clamping assembly includes a slide rail body 3, the rear outer wall of which is fixedly connected to the front outer wall of the rotating plate 25, and a slider 31 slidably connected to the outer wall of the slide rail body 3; a moving block 32 is fixedly connected to the rear outer wall of the slider 31, and the outer wall of the moving block 32 is slidably connected to the inner wall of the rotating plate 25; a moving plate 33 is slidably connected to the outer wall of the moving block 32; an electric push rod 34 is fixedly connected inside the bracket 2, and the output end of the electric push rod 34 is fixedly disposed on the rear outer wall of the moving plate 33; a gripper 35 is fixedly connected to the front outer wall of the slider 31, and an anti-slip pad is provided on the inner wall of the gripper 35 to prevent the lens body 36 from falling off; the lens body 36 is fixedly connected to the inner wall of the gripper 35, and the inner wall of the lens body 36 is disposed on the outer wall of the light source 19;

[0031] Specifically, when the front end of the light source 19 is fitted onto the inner wall of the lens body 36, the two are magnetically connected. The electric push rod 34 is activated to push the moving plate 33 to move, causing the moving block 32 to separate. The moving block 32 drives the slider 31 to slide on the outer wall of the slide rail body 3. The slider 31 drives the gripper 35 to move, causing the lens body 36 to be released. This achieves the effect of quickly disassembling and installing the lens body 36.

[0032] Working principle: When this structure is needed, the first motor 11, fixed to the inner wall of the outer casing 1, drives the first gear 12 to rotate. The rotation of the first gear 12 causes the rack body 13 to slide on the inner wall of the limiting slide rail 16, achieving a more stable sliding effect for the rack body 13. When it moves to both ends of the rack body 13, the first gear 12 pushes the buffer tooth 15 to move, causing the spring part on the spring limiting rod 14 to undergo elastic deformation. This allows the light source 19 to stop at both ends of the outer casing 1 for scanning or changing the lens body 36. During the movement, the rotating rack 17 set on the lower surface of the outer casing 1 allows the light source 19 to rotate under the action of the sector gear 18 fixed on its outer wall, further enhancing its stability. When changing lenses, the electric push rod 34 moves backward, separating the moving plate 33 and the moving block 32. The moving block 32 rebounds under the action of the spring in the slider 31, causing the slider 31 and the gripper 35 to slide on the outer wall of the slide rail body 3, thereby achieving the effect of clamping the lens body 36. After the lens is removed, the second motor 22 fixed inside the fixing block 21 drives the second gear 23 to rotate, causing the gear ring 24 to rotate. The rotation of the gear ring 24 will cause the rotating plate 25 to rotate, thereby switching the lens body 36 to be used. Under the action of releasing the clamping assembly, the effect of changing lenses is achieved. This structure can achieve the effect of keeping the light source 19 in place and continuously scanning the same type of code, and at the same time, it can achieve the effect of automatically installing and removing different lens bodies 36 as needed.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
